Specification forming part of Letters Patent N 0. 170,538, dated November 30, 1875 application filed March 18, 1875. I v

Tolalt whom it may concern:

Be it known that I, JOSEPH W. ELLIS, of

. the city and county of Philadelphia, in the State of Pennsylvania, have invented an Improvement in Machines for Turning Carriage- .Axles, &c., of which the following is a specislides, in such a manner that the different cuttersi turn separately the difl'erent-formed members of the axle, or other article, at one operation, as the carriage is moved onthe bedplate of the machine by means of a feed-screw .or other suitable device. The cutter-holder, which operates oneof the cutters, when it has finished its work, is drawn outward therefrom, whereby it is free to pass succeeding larger diameters by means of a lever connected with the next cutter-slide and box of the carriage; the said slide being connected with the preceding slide by means of an adjustable screw, whereby the outwardly-receding distance of v the; first-mentioned slide is determined. A

like arrangement is used in the combination of any additional cutter-slides with the others,

. for carryin g the preceding cutters outward to .prevent their contact with the piece to be turned after they have performed their work.

In the second place the invention consists of a swivel-plate, connected to the rear end of the above-mentioned carriage, and provided at one end with a gage for each cutter, whereby, ..by turning the gage end of the swivel toward the front of the machine, the cutters may be accurately adjusted for their work, after which the swivel is brought to its former position, with the gages out of the way.

In the accompanying drawings, Figure l is a plan view of my improved machine for turning axles, &c. Fig. 2 is a like view of thepatter-nrplate J. Fig. 3 is a cross-section, at the line as w of Fig. 1 Fig. 4 is a rear side elevation of the front end of the carriage F. Figs. 5 and 6 are a side and end "iews, respectively, of the cutter-holder G. Figs. 7 and 8 are like views of the cutter-holder G.

the clamping-pieces b and set-screws c; or, if desired, the clamping-pieces b may be dispensedwith. B is the movable head. E is the driving-pulley on the mandrel 0'. F is a carriage, provided with the sliding cutterholders G and G, situated in the box H atv the front end of the carriage, there being grooves in the bottom of the box for the reception of the tongues e e on the lower edge of the cutter-holders. and in the under side of the top f for the tonguese e on their up- 7 per edges, whereby the said cutter-holders have a sliding movement at right angles tothe line of movement of the carriage F, as the latter is moved forward by the feeding-screw rod I, or other suitable mechanism, there being lugs h and h,*respectively, on the lower edges of the cutter-holders, which slide in the slots i and '13 of thepattern-plate J, of the requisite form to guide the cutter K, for turn- --ing the bevel part ,of the axle, and the cutter K, for turning the straight parts as the carriage F is moved toward the stationay head B of the machine. The pattern-plate, which is shown in detail in Fig. 2, has dowel-pinsj j, by which it is held in place on the front shear of the bed-plate A. For passing the guide-lug h of. the sliding tool-holder G past square shoulders, or other abrupt parts-of the slot 11 of the pattern-plate, there is a lever, L, hung on the fulcrum-pin k in the rear side of the box H, the short arm I of the lever having a slot, 112, as seen in Fig. 4, which receives the outer end of the stud n, that proects from the rear side of the said tool-holder through a slot in the side of the box. The cutters K and K are adjusted by means of the gages M and M on one end of the swivelplate N. The plate is hung on the pin 0 at the rear end of the carriage F, and turned into the position seen in Fig. 3, with the gages at the rear side of the machine out of the way. I
